jmx4py offers a client API for Python similar to the existing Jolokia clients for Perl (jmx4perl), Java, and Javascript. Jolokia is a JMX-HTTP bridge giving an alternative to JSR-160 connectors. It is an agent-based approach with support for many platforms. In addition to basic JMX operations, it enhances JMX remoting with unique features like bulk requests or fine grained security policies. jmx4py builds upon the basic API and offers further features related to monitoring and controlling JVMs via JMX using Python.
